' fessor, citizen of Bavaria, residing at Munich,

.the form of a chain, of which 'the chain of cards may especial advantage in a library for the for-1 Bavaria, Germany, have .invented certain new and useful Improvements in Card- Chains for Systematic Filing of Memoranda; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhicli it appertains to make and use the same.

The present invention'relates to chains of cards for the systematic filing of memoranda aidthe like, and to improved means for collecting and filing the same.-

Itis alread known that receptacles of any kind, in th'e germ of pockets, frames, boxes,

etc., themselves containing memoranda-4 cards or the like, ma be linked together by means of buttons or liooks sliding in slots in such a way that a connected chain is formed, the several links of which may be either pushed together for the purpose of storing, or pulled apart to make the whole easier to survey.

It is also known that any desired number of memoranda-cards may be c nnected in e separate units may at any time be linked in any desired orr'ler.

The c ain of cards forming the sub'ect of the present invention is distinguishe from the above-mentioned known devices by each single' memoranda-card having at the tolp a tongue and urther a slit or loop paralle to the upper edge, through which the bent-down toilue of the preceding card can be passed, sot at'each card can slide u p and down over the surface of the -preceding card without disengaging the chain. i

A chain of cards may advantageously be employed in all cases where it is necessary to arrange systematically registers, memoranda or the like .which undergo a constant change, or-where it is desired to file a constantly accumulating amount of short Y notices, the ilial .bulk of which will not be too reat. But the use of card-chains for more vo uminous material is in no Wa excluded. Thus mation of a tem orary catalogue of books newly added, or or maki a separate catalogue of smaller divisions o larger collections of books (theses, treatises and lists of those books which are still incomplete), further employed with for all kinds of registers of addresses7 lists of members, for compiling programs, announcements, bills of fare, tableaux, etc., which undergo a change every day, but yet consist on the whole of a certain number of fixed components in daily differing arrangements. These are a few of the principal uses to which such a card-chain can be put. lts use, however, is not limited to written memoranda, for every group of diiering units which can be arranged singly within the space of one line without perceptibly increasing the thickness of the card and which require and are adapted for systematic filing may be iled by means of card-chains; for instance, collections of patterns, color-samples, etc. v

The essential advantage of this card-chain as compared with other known similar devices lies 'in the fact that the. cards can slide over each other without becoming disengaged, so that the chain of cards when not in use can be pushed together and will then take up very httle space.

In t e accompanying drawings Figure 1 is an elevation of a unit of a card chain embodying the invention; Fig. 2 is a similar view of another form of unit; Fig. 3 is a perspective view of a unit according to Fig. v1

with its tongue partially bent; Fig. 4 represents the card chain closed; Figs. 5 and 6 are respectively a front and r'ear elevation of the chainv extended; Figs. 7 and 8 re resent in front and rear view another form o unit; and Fig. 9 is a fragmentary view of a further modiiied form.

yReferring to the drawings, in Fig. 1 is,

shown a plan view of such a card unit of a chain in its simplest form of construction I with-a tongue b and slit c.

Figs. 2 and 3 show another form of such a vcard unit in two different stages of construction; in this brfn the openin for the tongue consists of a slit in the form o a pocket madev by pasting or otherwise attaching two dpieces of cardboard e e to theiront ofthe car a, an o n space being left in/the middle equal to tile?) Width of the tongue, (Fig. 2) `upon the pieces e e a stri of cardboardor they like is pasted, its wid being equal to the width of the cardo., and its-upper edge forming with the` help of the side-pieces e e the upper boundary of the opening' or groove for the ton e b.

lgs. 4 to 6 show a card-chain composed of several such cards or card units, in Fig. 4

the cards.

formed is pulled out or opened by lifting the closed orpushedtogether in the form of -a` pack for convenience of storing Whennot in use, and in Figs. 5 and 6 open or pulled out for use and hung up on a nail by means of the hole in the tongue of the last card, Fig. 5

ig. 6a backyvieW of the Referring again to 2, it Will be seen that the free s ace i, which is provided to re-` duce bulkan prevent undue friction, does groove for the tongue; a art of the carda extends across the topof) theback of the groove, thereby also preventing a rising of tongue in that the form of construction shown in Figs. 2 and 3.

It Will be obvious that the examples iven above are not the only possible forms o construction for such card units of a card-chain,

but the essential features in all forms of con-- struction Will always be the tongue andthe slit, pocket, groove, loop of Wire or metal or similar spring or device, however formed for the reception of the tongue. Obviously also each card-chain unit may be provided With tWo tongues b/ and two openings'c, grooves or the like instead of one as indicated in Fi 9; ,this arrangement ma advantageous y be adopted in the case of argesized cards. E i

A card-chain is formed from a number of card units by pushing the tongue of the second card into or through the groove or slit of the first card, then the tongue of the third card through the lslit of the second, and so on for all cards, the order of precedence of coursebeing decided by the inscriptionson lf noW the pack ofcards thus rst card by means of its ton ue (Figs. 5 and 6), a space on each card-equa togthe distance of the slit from the upper edge of the card will become visible (Fig. 5); this space alone is intended for the inscription, memorandum, etc., and 4therefore the opening out of the pack result infall inscriptions becoming at once visible.

A single card ofy a chain c an be easily -re `moved or aneW card inserted at any desired point if the chain is disengaged by lifting the ton ue out of its' groove at this point.

can e most conveniently accom lished if the chain is hung up as shown in ig. 5 both hands being then free to manipulate the cards; a better su ervision oficthe Wholeis also hereb possib e. But it is' also practicable to take thepack in the left hand and to 1 leas-t equal to the Widt not extend to the uppermost limit ofj the draw it slightly a art with the right, Which method has the a vantage of makin it possible for the operator to sit at a tabde when Working.
